Specification of-Letters Patent. Patented June (,v 1922,

Application filed December 23, 1920. Serial No. 432,811.

To all whom t lmay concern y Be it known that FRANK KALMAN, subject of the ling of lGrreat Britain and lie land, residing at 80 Bathurst Street, Sydney, in the State olf New South YVales, Commonwealth of Australia, have invented new and useful Improvements in Trousers, of which the following is a specification.

This invention relates vto mens trousers and has particularreference Vto means by which the trousers are held in. vposition around the waist or' the wearer.

` The object oli' the invention is to provide a simple and etiicient means whereby the trousers are heldin position around' the waist ot' the wearer without the use of braces or belt and at the same time to provide means whereby the circumferential length around the waist will be automatically increased or decreased according to the expansion or contraction "ot' the body of the;

wearer. K

To effect the object in View the trousers are provided with a loose verticalpleat situated at each side of the trousers, preferably immediately behind the side seams. These pleats are so termed asy to gradually diminish to zero at or near the bottom of the side pocket openings. The innermost tace of each of these pleats is secured bymeans ot stitching or byA a button to one end ot' a rearwardly extending strip of elasticv webbing` the other ends ot such webbing being secured at points about midway between the side seams and the centre ot' the back, while the outermost face ot' each pleat is secured in asimilar manner to a strip of elastic webbing` which extends thence torwardly,

the other end of each strip being4 secured The toremostends of the strips of webbing which extend forwardly are passed through yopenings' made inthe side seams land from thence along the inside front ol" the trousers to the point at which they vare attached.

stitching securing the .liningto the material of which the trousers are made. This se-` cures the webbing to the ytrousers along practically its entire length and aty the same time prevents it from rubbing against'the inner clothing of ythe wearer. y A

ln a modication, the rearwardly extending webbing consists ot'one strip instead of two, one end/ oit this 'strip being stitched to atabprovided with ua button @hole enigme of the P19/Lt 011 the right handside and assin thence throufrh a=tube Ior casino f b D i l b formed across the inside rear. waist of the trousers, to the left hand sfide 'wherethe 46() gaging with a button upon the innermostr` other end of the webbing is similarly secured to the innermost tace of the Apleaton that side. l l l f The application o'l the invention will be more readily understood by referring to the accompanying sheet ofdrawings in/which Fig. l illustrates one method Ofapplying the invention, the figure being a perspective y'view ot the waist portion( of pair of trousers with the lining removed.

Fig. 2 is a section' taken o-nthe line A. of Fig. l with the lining in position.

Fig. 3 shows that portion ofthe back part ot the tiousers in which the triangular piece of webbing is inserted, while, l

Fig.y 4- fillustrates another method of applying the invention .the figure being'the waist' .portion of a pair of trousers 4with the lining removed.'

ietore entering into the detailed description of these drawings attention is called to the tact that there are many different methods by which my invention may be put into practical use and those vherein described have been chosen as the most suitable for-the purpose oit describing and illustrating how the invention is to be applied.

vteferring now more particularly to Fig. l. The pleats 6 are placedpreferably one at each side of the trousers Z immediately" to the rear of the side seams'? so that'they may be made to taper .oit `to zero at or near the bottom of ythe pocket openings 8. The outermost'surface 9 of these pleats is provided with a button 10 thatv engages with a:

button hole l1 in a tab l2 secured toone end .of a strip oli'elastic webbing 13'. lThis elas- `tic webbing is passed inwardly through an n 'opening 'le in the seam 7 ofthe trousers, into and along a tube or casing formed by placing 'a piece of lining upon the inner surface of the trousers and securing them together' by means of two parallel lines of stitching. This tube or casing extends from a point 15 infront of the seam to a point 16 about midway between the seam and the middle front of the trousers. The end of the webbing most remote from the pleat will be' firmly secured to the material by stitch` ing 17 or it may be provided with a tab and button hole to engage with a button secured upon the inside of the trousers as shown at 17a1 in Fig. 4. A strip of elastic webbing 20 is similarly secured at 19 to the in nermost face 18 of each pleat, but this piece will extend from the pleat rearwardly to a point 21 about midway between the pleat and the centre of the back of the trousers where it will be securely fastened by means of stitchingy or by a button vand button hole as previously explained.

Referring now to Fig. 3, a portion of the trouser material in the centre of the back is cut away and a triangular piece of elastic webbing 22 inserted and secured by stitching 23 in a manner that will be readily understood.

`The modification consists of the substitution of one piece of elastic webbing 24 for the two rearwardly extending pieces 20. This modification makes the inserted triangular piece 22 unnecessary, reduces the cost of manufacture and incidentally all these pieces of webbing may be quickly removed or replaced as required.

Fig. 4 shows the modification, the ends of of the webbing 24 being provided with tabs 25 vin each of which are button holes that engage with Vbutton 26 upon the innermost face of ther pleat 6, and extend rearwardly from pleat to pleat. rllhis webbing 24 will pass through a tube or casing extending approximately from the point 27 to vthe oint 28.

Although in Figs. 1 and 4 the tube or casing, which is partly formed by the lining, is not shown it will be readily understood by referring to Fig. 2 in which 29 is the outer surface of the trouser material, 13 the lining, 31 the elastic webbing, 32 and the two parallel lines of stitching securing the lining to the trouser material.

In operation the expansion of the body of the wearer will cause the trousers to eX- pand by`opening out the pleats 6 and eX- tending the elastic webbing 13 and 20, 01H13 I and 24. ln this extended position the `elastic l webbing 13 is pulling in the opposite direction to either the elastic webbing 2() or 24 as the case may be, so that pressure is maintained aroundthe waist of the wearer until contraction of the body takes place, when, as the strain upon the elastic webbings 13 and 20 or 24 is released they will gradually contract and in doing so will automatically carry the pleats 6 with them and cause the l latter to assume their normal size. p

From the nature of this invention it will be clearly seen that although it has been described with special reference to trousers, it is equally applicable to other wearing apparel, but more particularly to that class which hangs from the waist.
